+/** ()A code specifying the transformation to be performed on the sample values: |
+ * 0 No transformation. |
+ * 1 If the image has three color components, transform RGB values to |
+ * YUV before encoding and from YUV to RGB after decoding. If the |
+ * image has four components, transform CMYK values to YUVK be- |
+ * fore encoding and from YUVK to CMYK after decoding. This option |
+ * is ignored if the image has one or two color components. |
+ * Note: The RGB and YUV used here have nothing to do with the color spaces de- |
+ * fined as part of the Adobe imaging model. The purpose of converting from RGB |
+ * to YUV is to separate luminance and chrominance information (see below). |
+ * The default value of ColorTransform is 1 if the image has three components |
+ * and 0 otherwise. In other words, conversion between RGB and YUV is per- |
+ * formed for all three-component images unless explicitly disabled by setting |
+ * ColorTransform to 0. Additionally, the encoding algorithm inserts an Adobe- |
+ * defined marker code in the encoded data indicating the ColorTransform value |
+ * used. If present, this marker code overrides the ColorTransform value given to |
+ * DCTDecode. Thus it is necessary to specify ColorTransform only when decod- |
+ * ing data that does not contain the Adobe-defined marker code. |
